3 Claims. 1

This invention relates to a metal ventilator or window structureparticularly for use in connection with glass blockwalls.

One of the objects of the invention is to provide a structure in whichthe sash can be readily removed or adjusted from the inside of thebuildin and the storm sash or screen also positioned from the inside.

A further object of the invention is to construct a metal ventilator orframe in which the bottom rail is so constructed as to prevent thedischarge of condensation within the building.

More specifically this invention comprehends a one piece welded frameshaped for association with glass blocks, the frame being provided witha sash hingedly supported to permit suitable adjustment in any kind ofweather, 'and being adapted for seating engagement with weatherstripping of sponge rubber to insure against leakageof air and water andto provide a better appearance for the assembly in use.

Reference will be had to the accompanying drawings forming a part ofthis specification and wherein like characters of reference designatecorresponding parts throughout the several views in which Figure 1 is aperspective view of the assembly showing the sash in open position,

Figure 2 is a vertical section through the structure in the positionshown in Figure 1,

Figure 3 is a horizontal section on line 33 of Figure 2, and

Figure 4 is an enlarged vertical section showing a screen in position inthe frame.

The frame structure is formed by pre-shaping a metal strip of suitablelength and then bending the strip to form the four sides of the frame.The ends of the strip are of course welded together in the usual manner.If desired this same frame could be made of two or more sectionsalthough obviously the unit structure is preferable.

Generally the frame is of channel form with the outer flanges l andinner flanges 2 extending outwardly as clearly shown in the drawing andadapted to lie flush with the outer and inner wall faces respectively.The lintel and side members of the frame are formed medially with aninwardly extending recess 3, which defines within the frame structurethe outer wall 4 and the inner wall 5 which walls function as stops forspacing and positioning the sash 6 and screen frame I, it beingunderstood that screen frame 1 may have substituted therefor a stormsash when desired. The sash frame is formed of angled metal with oneflange 9 extending vertically and abutting the inner marginal edge ofthe glass It, and the other flange ll extending normally in a horizontalplaneacross and substantially beyond the edge of the glass pane. Theprojecting portion of the flange l l forms a support for the sealingmaterial l4 and provides a relatively wide lower base portion forcooperation with the sealing member. The sealing member is in the formof a vertical fiat continuous strip l5 which engages and seats againstthe inner face of wall 5 at the top and sides of the frame. At the sillthe sealing member includes the horizontal inwardly extending portion l6which seats upon the sill between the wall 5 and the inclined sillportion I'l and upon this portion l6 of the seal the lower edge of thesash frame 8 seats. The seal extension I6 is of the same width as thesash frame 8 and the parts are so arranged that in closed position theouter edge portion ll of the sash base is forced into the seal to insureagainst leakage. The clearance between the sash and the sash pocket ofthe frame is just sufficient to permit the use of the sealing member asabove described.

The inclined face of sill portion ll of the frame terminates at a pointimmediately adjacent the inner face of the sash frame 9, and in this waythe wall I! forms a pivot for the swinging movement of the sash frameduring its adjustment, and in full open position the sash frame will beat rest on its upper angular face.

The hinge structure is in the form of a pair of links 20 and 2| hingedtogether at 22, with the link 20 pivoted to the projecting ear 23 of theplate member 24 fastened to the inside of the frame. The link 2| ispivoted at 25 to the ear 26 of the plate 21 secured to the inside faceof the sash member 8.

The screen which will be of a size to snugly fit the recess in the outerface of the frame, will be secured in place by spring clips 30 whichproject inwardly to snap over inwardly projecting lugs 3| formed inopposite inner faces of the frame stop. The screen frame is shown asformed of two angular frame members 32 and 33, the angular frame member32 having the inwardly projecting flanges 34 and 35 which overlap it atmarginal edges 36 to clamp there between the screening 31. The framemember 33 of the screen frame overlies the screen frame 32 to concealthe fastening portion of the frame and the joint between the frame andthe screen. These screen frame sections may be secured together in anysuitable manner as by welding. In this type of screen the screen clothextends at the marginal edge of the frame which in the present instanceis substantially flush with the outer flange I of the window frame. Anextension 38 is welded or otherwise secured to the top of the sash 8 toform a handle for moving the sash on its hinges to a predeterminedposition at which it may be locked due to the inherent frictionalquality of the joints of the supporting hinges.

From the foregoing it will be seen that a structure has been providedparticularly suited for use in connection with glass bricks or blocksand in which the storm sash or screen can be positioned from within thebuilding. This is particularly desirable in high buildings. As to theadjustment of the sash frame 8 the hinges 2[I2l are of such a nature asto be retained by friction at any adjusted position. The provision ofthe watershed I! in the window frame tends to guide the sash in itsadjusted position and at maximum open position forms a support for thesash structure. This first result is produced by the fact that the outerbottom edge of the sash is normally in the recess formed at the junctionof the angular watershed l7 and the frame during the swinging movementof the sash to open position. When the sash i8 is in fully open positionit will lie flush upon the angular face of the watershed l1 and besupported thereby.

What is claimed:

1. In combination with a window frame including a lintel, side walls,and a sill, said frame being provided with medially arranged inwardlyextending spaced wall portions at the lintel and side walls definingstop means for a frame, the sill of said frame including an upwardly andinwardly extending continuous angular portion spaced inwardly of theinner stop member, a sealing element facing the inner face of said stopmember, said sealing element including a horizontal flange overlyingthat portion of the sill outward of the angular extension and betweensaid extension and said stop members and forming a seat for a sash, andhinged frictional supporting arms connecting the upper portion of saidsash to said frame to permit the inwardly angular swinging adjustment ofthe latter on said 4 seat to a position determined by said angular 'portion.

2. The substance of claim 1 characterized in that the sill portion ofthe sealing element of said frame includes an upright portion extendingfrom sidewall to sidewall, which upright portion merges with the sealingelement abutting the lintel and side walls of the frame.

3. In combination witha window frame including a lintel, side walls, anda sill, said frame being provided with an inwardly extending continuouschannel providing spaced wall portions at the lintel and side walls, thesill portion of said frame having an upwardly and inwardly inclinedsurface extending from sidewall to sidewall of said channel a distanceto permit the seating of a sash, and a pack-ing member between the sashand frame, said packing member comprising soft rubber wall portionsseated against the inner wall forming said channel and a bottom portionof L-shaped cross section adapted to be positioned on the sill, one ofthe legs of the bottom portion of said packing lying on a horizontalplane on the flat portion of the sill outwardly and adjacent to theincline portion of the sill and being adapted to receive and seat thelower portion of the sash and means for maintaining the sash in adjustedangular position.
